There is just something very blatant about Patty's commandeering of Charlie Brown's tricycle. He loves his trike and pleads about how he was looking forward to tooling it around, but to no avail. She rides off, the look on her face indicating that she spares not a thought about CB's opinion. She feels no shame, and neither does she feel vicious pleasure. It is a tricycle; Patty likes riding tricycles; anything standing in her way, then, of riding the tricycle is an obstacle to be overcome.
This is really more of a Lucy move, but she has yet to come fully into her infernal powers.
